will cause the leaves of the book to separate 7 and move out of the fixed part of the container as the cover portion thereof is opened; third, in which the sheets are mounted in groups, any of which may be removed from the container, the sheets composing the group thus removed may then be redistributed, removech or replaced, at will and the group rebound in the book; fourth, in which the sheets are so mounted in the container that the pages will lie fully open and substantially flat, irrespective of whether they are in one portion or another of the book; fifth, in which all the sheets are cut in identical manner and can therefore-be used in any portion of the book; sixth, in which the sheets are fastened in the book by means of removable metal binding which is locked in the container and which may be used over and over again; seventh, in which the book cover is hinged to the back, and the hinge pintle thereof supports a plurality of intermediate or secondary hinge links, to each of which two groups of sheets are pivotally attached, whereby the book willopen justas readily and completely at one portion as at another; eighth, in which such secondary hinge links are formed so that when one is reversed its primary'hinge barrels will fit between those of the other hinge link and yet so that in either case the secondary hinge portions thereof are in exactly corresponding positions, so that the sheets secured to the one hinge link will bein the samevertical alignment as those secured to the other hinge link; ninth, in which the back, top and cover of the container, the secondary hinge links, the locking bars, and the metal sheet binding may all be stamped and pressed out of metal, thereby keeping the cost of such conitainers down to a low point; tenth, in which the cover of the container is secured to the pintle of the primary hinge and said pintle is spring actuated to keeprthe cover closed: and eleventh, toiprovide a removable sheet book Which is neat in appearance, cheap to make, easy to manufacture in large quantities, and which may be used for a great variety of purposes.

I attain these and other objects by the devices, mechanisms, and arrangements illustrated in the accompanying drawings, 1n

I V 7 Similar numerals of reference refer to horizontal line in the The primary use to which this book is designed to be put is fora street directory where it'will be supported in vertical posipurpose towhich bookmay be put.

The book, therefore, comprises a metal container with a front cover hinged theresimilar parts throughout the several views. 7

tofand groups o'f'leaves secured therein. 1

Theccontainer is intended to protect't-he leaves from the inclemency of the weather and from wear. In order to enable the book to be kept up to date in its information, without having to reprint a large portion of it at each correction, it is constructed on the looseleaf order in which each group of sheets may be removed from the binding and any sheet of the group removed and, if desired, one or more new sheets substituted and then the entire group reinserted in the book, and such removal and substitution will be easily and quickly performed without having to remove the container from its permanent support. In order to enable the book to be easily opened at a desired page, using one hand only since the other hand is often engaged in carrying articles, when used as a street directory, 1 have arranged the parts in such manner that the leaves are drawn out of the container as the cover is opened, whereby the hand which holds back the cover, against its closing spring, can readily pick out the page at which it is desired to look, and so that any such page will lie flat and open and thus can readily be read. Also all four pages of each sheet may be used.

Referring now to the drawings, the coutainer comprises a box formed of pressed aluminum, or other suitable material, having a back plate 1, by means of which it may be fastened in vertical or inclined position to the support (not shown), if desired; an edge plate 2; and a top plate 3. The top plate 3 may extend over the container to a greater depth than the edge plate 2 and also may ex tend to a greater width than the container. thus forming an etlfective roof for the book contents. The top plate 3 may also be bent up into a front plate 4, on which suitable lettering may be placed for the purpose of identification or for indicating the street intersection at which the book is placed, if desired.

A cover plate 5, also preferably formed of pressed aluminum, is provided and is adapted to close the front of the container. In general, I prefer to omit any closure of the bottom edge of the container, thereby facilitating reaching and turning the leaves of the book when in use, but it is to be understood that such a bottom may also be provided, formed integral 'ith the back plate 1, bent forward, or with the cover plate 5, bent backward. The cover plate 5 may also have suitable lettering: on its surface, as above ll'lQlllTlOllCtl for the front plate 4. i

The back plate 1 is bent forward along its left edge, at an angle, as shown, to form the inclined portion 6. and the edge of this portion 6 iscut and rolled to provide a plurality of hinge barrels 7. four are shown in the drawings. The cover plate is complementarily bent rem-ward along its left edge to form the in lined portion 8, and the edge of this portiont; is cut and rolled to provide separated from the center two pairs by spaces which are tilled by the barrels of the hereinafter described secondary hinge links. A single pintle 1t) pass-es through all the barrels 7 and 9 as well as through those of the said secondary hinge links, and also passes upward through the top plate A small slot 11 is made in the pintle 10 (Fig. 11) about half way down the side of the book, and a thin plate 12 is secured to the part 8 of the cover 5 and enters the said slot 11, thus attaching the cover plate to the pintlc in such manner that the pintle will turn with the cover as it is opened or closed. A spring 13, preferably a flat coiled spring, issecured to the top of the pintle 10, by having its inner end enter a slot 1% in the upper end of said pintle, and is'enclosed in abox or cap 15, which held from rotating by means of lugs 16 which pass through suitable slols l? in the top plate of the container, said spring 13 being secured at its outer end to said box 15 by being bent through a slot therein. Thus the tension of the spring 13 can easily be regulated by raising the cap 15 sufficiently to draw the lugs 16 out of the slots, turning the up, and reinserting the lugs in position. Thus it will be seen that the above described parts form a container which is made of only two pieces of metal stamped and pressed to shape and adapted to hold and to protect the sheets and adapted to be used in vertical or in any 7 other position, as desired.

The secondary hinge links 18 and 19 (Figs. 3 and at) are also made of stamped and pressed aluminum. or other suitable material, and are identical. However, the hinge link 19 is assembled in the book in reversed position from the hinge l nk 18. Each hinge link consists of a plate suitably cut out. and bent to form the series of primary barrels 20 and 21, respectively. through which the above-described pintle 10 passes when the book is assembled. Thc e barrels; are all joined by the vertical plates which time cause all the parts to turn tog'rethor on th hintle 10. A double seriesot hooks 33 and 24: extend from the plates the hooks 2 turning back in one dir ction while the hooks 24 turn in the op 'iosite direction. The books 23 and 2% 11'6 a WTEQ'Gti side by side. In the drawings: six sets of such hooks F23 and 21: are shown, for each of the hinge links 18 and 19.

A lock bar is also made of stamped and pressed aluminum and is shown in ig. 7. This consists of a plate bent into U-shape so as to have two legs 25 and a central web 26. It is slightly longer than either of the two hinge links 18 or 19. The central web 26 is cut at various points positioned to come opposite to the hooks 23 and 24,. above do 3 with the hooks and thus a space is made opposite the openings of these hooks of sufficient size to permlt the entry or withdrawal of the binder wire into or out of said hooks.

The sheets 27, of which the book is formed, are provided with aseries of cuts or slots 28 on their center line, and are folded on K this line, (Fig. These slots 28 are positioned and spaced to come opposite to the hooks 23 and 24, of the hinge hn s above described, and they are equally spaced and symmetrically placed relatively to the top and bottom edges of the sheets 27,, so that each sheet is exactly like every other sheet and can be printed with either edge uppermost. The sheets are folded one within the other to form a group, and all the slots in the group align to permit the binder wire offsets to pass therethrough. V p

The binder wire 29 (Fig. 5) is made of stiff wire or cut from sheet metal, and is provided with offsets 30, each positioned in line with the slots 28 of the sheets 27 and adapted to pass therethrough into the hooks 23 or 24. The said offset portions 30 thus form the secondary pintles of the binding and as they pass through all the slots in the sheets and lie inside the inner fold of the group of sheets they bind the sheets to the hinge links, and the hinge links bind them to the container, and the lock bar closes the hook openings and prevents the accidental removal of the group of sheets. As above, the binder offsets extend through the sheets and said extending portion forms, with the sheets, a closed rectangular ring, one side of which engages the corresponding hook of the hinge link, and is free to turn therein as a. hinge pintle.

In opening the book, the cover plate 5 swings on the container and turns the pintle 10 with it. The barrels 20 and 21 of the hinge links tend to turn with the pintle '10 on which they are mounted andthus, as the cover plate is opened, the leaves tend to come out of the container and this effect is aided by the fact that all the barrels 20 and 21 of the hinge links lie above and are supported'by the barrels 9 of the cover and therefore tend. to turn with their support, thus the book is automatically opened out,

the leaves separating, as the cover of the book is opened, thus greatly facilitating the finding of the page on which the desired information is recordedn The book therefore consists of a. metal binding or container, having the front cover hinged to the rear to open out fiat; two secondary hinge links supported on the same hinge as the front cover, and dividing the sheets in the book into two distinct and independent groups; and four groups of leaves, each independently bound to one of the hinge links and free to turn thereon as on a secondary hinge, two of the groups being 7 supported on one hinge link and two on the other; together with a locking bar on each hinge link to prevent the accidental removal of either of the groups of sheets mounted thereon.

Having therefore described my invention, what I claim, is

1. A book comprising a supported metal pintle; a metal hinge linkmounted on said pintle and provided with a series of hooks; a group of sheets, folded one within the other and slotted along portions of the fold; and a metal binder lying within the fold of the innermost sheet of said group and bent with, offsets, each ofiset extending through the corresponding slot of said group of sheets and projecting therefrom into engagement with the corresponding hook on said metal link. a

2. A book as set forth in claim 1, wherein the hinge link-is provided with a double series of hooks, lying side by side, the hooks of one serieseach adapted to-receive the corresponding projecting offsetportion of the metal binder of one group of sheets, and the hooks of the other series correspondingly vided, each similar the one to the other, but

one hinge linksmounted in reversed position from the other, each comprising a plate extending parallel with the pintle, a plurality of hinge barrels extending from one edge thereof and encircling said pintle, the bar rels of one hinge link fitting above the barrels of the reversed hinge link, and each provided with a plurality of hooks extending from the other edge, each hook adapted to receive the corresponding projecting offset portion of the metal binder, the hooks of the several hinge links being similarly positioned, each to each, relatively to the upper and lower edges of the book.

5. A book comprising a supported metal pintle; a hinge link mounted thereon and provided with hooks; a group of sheets, folded one within the other and slotted along portions of the fold; ametal binder lying within the fold of the innermost sheet of the group and bent with oii'sets, each oli set extending through the corresponding slot of said group of sheets and projecting therefrom and engaged by the corresponding hook; and removable means for blocking the openings of said hooks, whereby said binder and groups of sheets are locked in position.

6. A book as set forth in claim 5, wherein said locking means comprises a bar slidably mounted on said hinge link and slotted to permit the hooks to pass therethrough, the edge of the slots blocking the openings of the hooks.

T. A book as set forth in claim 5, wherein said locking means comprises a bar slidably mounted on said hinge link and slotted to permit the hooks to pass therethrough, the slots thereof extending downward and widening below the normal relative position of the hooks, whereby when the bar is in its normal position the edges of said slots block the openings of the hooks but when it is in raised position the edges of the widened portions are removed from the hooks to permit entry thereto.

8. A book comprising a container; a pintle mounted on the container to form a hinge; a cover mounted on said pintle; a group oi? sheets within the container; and means for securing said group of sheets to the pintle.

9. A book as set forth in claim 8, wherein the cover is attached to the pintle and the pintle is rotatably mounted on the container, whereby the pintle turns with the cover as it is opened or closed, and whereby the group of leaves is moved out of or into the com tainer as said pintle turns.

10. A book comprising a container; a pintle rotatably mounted on the container to form a hinge; a cover attached to said pintie and rotating therewith to close the container; a hollow cap into which the end of said pintle projects and adjustably attached to said container; and a spring coiled around said pintle and connected at its ends to said pintle and to said hollow cap, whereby the force applied by the spring to the pintle will move the cover to close the container, and whereby the said force may be adjusted by adjusting the cap on the container.
